Cognitive radio and dynamic spectrum access can reform the way that radiofrequency spectrum is accessed. Problems of spectrum scarcity, coexistence, and unreliable wireless communication that affect industrial wireless networks can be addressed. In this paper, a game theoretic dynamic spectrum access algorithm that improves upon on a hedonic coalition formation algorithm for spectrum sensing and access is presented. The modified algorithm is tailored for faster convergence and scalability and makes use of a novel simultaneous multichannel sensing and access technique. Results to demonstrate the performance improvements of the adapted algorithm are presented and the use of different decision rules are investigated revealing that a conservative decision rule for exploiting spectrum opportunities performs better than an aggressive decision rule in most scenarios. The algorithm that was developed could be a key enabler for future cognitive radio networks.

认知无线电网络的快速收敛合作动态频谱接入

认知无线电和动态频谱访问可以改变访问射频频谱的方式。可以解决影响工业无线网络的频谱稀缺，共存和无线通信不可靠的问题。本文提出了一种基于博弈论的动态频谱访问算法，该算法是对享乐联盟形成算法进行频谱感知和访问的一种改进。修改后的算法专为实现更快的收敛性和可伸缩性而设计，并利用了新颖的同步多通道感应和访问技术。结果表明了改进算法的性能，并研究了不同决策规则的使用，结果表明，在大多数情况下，利用频谱机会的保守决策规则要比积极决策规则执行得更好。所开发的算法可能是未来认知无线电网络的关键推动力。
